To all whom it may concern.-

Be it known that we, SAMUEL T. VVELLMAN, CHARLES ILWELLMANJOHN W.SEAvER,and THOMAS R. MORGAN, citizens of the United States, andresidents of Cleveland, Ohio, have invented certain Improvements inCoke-Loading Apparatus, of which the following is a specification.

The object of our invention is to provide means whereby hot coke from acoke-oven'or a series of ovens may be quenched and loaded in cars with aminimum expenditure of human labor, the apparatus being also of suchcharacter that large quantities of coke can be handled in the shortestpossible time and can be delivered into cars on two or more paralleltracks instead of the delivery being limited to a single line of cars,as in other coke-loading machines with which we are familiar.

In the accompanying drawings, Figure 1 represents in side elevationsufficient of a coke-loading plant to illustrate our invention. Fig. 2is a similar view with some of the parts in a different position. Fig. 3is an end view of one of the loading-pans and part of the trolleymechanism for handling the same; and Fig. 4 is a View on a reducedscale, showing a modification of part of the invention;

In Fig. l of the drawings,l represents part.

of one of a row of coke-ovens, and 2 a cantaliver gauntree crane, havingits legs running upon rails parallel with the row of coke-ovens, thiscrane spanning two or more railwaytracks, upon which are intended to berun the cars to be filled with the coke. The crane has a travelingtrolley 3 for handling any one of a series of pans 4., suitablysupportedupon.

walls 5 and 6 in front of the row of. ovens, each of these pans servingboth as a quenching and loading pan, being open at the inner end or endnext the oven, so as to receive the charge of hot coke pushed therefromand which after being deposited in the pan can be quenched by waterdirected upon it by means of attendants on the platform in front of therow of ovens, the quenching-water discharging into the channel 7 betweenthe walls 5 and 6, from which it escapes through a suitable drain orsewer pipe. The pans 4 may be of any suitable length, and-the trolley 3is provided with any desired number of depending hangers, from which thepan may be suspended, there being by preference four of these hangers,one for each corner of the pan, as will be clearly seen by reference toFigs. 1 and 3. that end of the pan farthest from'the ovens the front endand the open end of the pan,which is nearest to the ovens, the rear end.The trolley 3 is preferably provided with a transversely-rigid dependinghanger 9 for each of the rear corners of the pan, as shown in Fig. 3,this hanger having at its lower end a hook 10 for engagement with ahook,eye, loop, or equivalent structure ll'at said rear corner of the pan. Alocking-bolt12, controlled in its movement by a solenoidor otherelectromagnet 13 on the hanger 9, engages with the eye or otherattachment on the pan after-the same has been caught by the hook andprevents any accidental disengagement of the two, as shown clearly inFig. 2, where the bolt is in its lower or looking position, as it closesthe open side of the hook and prevents the same from being disengagedfrom the eye on the pan. The eyes or other lifting attachments 14 at thefront corners of the pan are engaged by swinging books 15, carried bysuitable hoisting-tackle 23,depending from ahoisting-drum 16 on thetrolley 3, as shown in Figs. 1 and 2. The depending portions of thehoistingtackle are inclosed in a telescopic incasement 17, the lowersection-of which is provided with fulcrum-bearings for the swinginghook, as shown, and to which the hoisting-tackle is attached, by whichconstruction said hoisting-tackle is protected from being injured by thesteam' and hot gases arising from the coke and at the same time is heldina rigid vertical position, so that no swinging or swaying of theloaded pan is possible after the same has been picked up by the trolley,thus providing transversely-rigid hangers and lifting devices, to whichthe pan is suspended at its four corners. A solenoid or otherelectromagnet 19 on the telescopic incasement of For convenience we willdenominate portion of the hook 15, thus holding the same in positiveengagement with the eye on the pan when the solenoid is energized in themanner well understood by those skilled in the art.

It will be understood that the crane is provided with the usual electricor other motive power apparatus for moving the same, for traversing thetrolley, and for operating the hoisting mechanism, such motive power apparatus, as well as the electromagnets 13 and 19, beingunder controlofan attendant in the cab 20 of the crane.

The operation of the apparatus is as follows: The pan resting upon itssupports in the inclined position, as shown in Fig. 1, is loaded withhot coke, pushed into the same from the ovens, and after said'colre hasbeen properly quenched the crane is moved into line with the pan and thetrolley3 is run forward on the crane until its hooks 10 and 15 haveengaged with their corresponding fastenings on the pan, whereupon theconnections are locked, as shown in Fig. 2, by means of the magneticdevices described, and the front end of the pan is then lifted byoperating the hoisting mechanism of the trolley until the pan has beenraised clear of its fixed supports and assumes a substantiallyhorizontal position. The crane and its trolley are then operated untilthe rear end of the pan occupies the proper relation to a car into whichthe contents of the pan is to be loaded, whereupon there is a furtherlift of the front end of the pan, so as to tilt the same and cause itscontents to be discharged into the car, as shown by dotted lines in Fig.2, after which the operations are reversed and the pan is restored toits position on the fixed supports 5 and 6 preparatory to receivinganother load. As the entire handling of both the loaded and empty pansis thus effected by a single attendant, the amount of human laboremployed is reduced to a minimum, while the use of a number ofindependent pans for each handling apparatus and the provision forloading oars upon two or more tracks insures the expeditious handling oflarge masses of coke in the least possible'time, and consequentlyreduces the expense of loading to the lowest possible figure.

In Fig. 4. we have illustrated a modified embodiment of our invention inwhich a trolleycarrying bridge 21 travels upon runways on elevatedsupports 22 and 23, one of said elevated support-s running along the endof the row of ovens l and the other being outside of the tracks whichreceive the cars to be loaded.

If desired, hoistingtackle may be employed for the rear portion of thepan as well as for the front portion of the same; but the use of a rigidsupport for said rear portion of the pan is preferred because of itsgreater simplicity and convenience.

Having thus described our invention, we claim and desire to secure byLetters Patent-- 1. The combination with a crane structure, of a trolleyadapted to run thereon, depending and transversely-rigid lifting andsupporting devices carried by said trolley, a loading-pan, and supportsto hold the pan in position under the crane structure, so that it can beengaged and lifted by the supporting and lifting devices, substantiallyas do scribed.

2. The combination of a traveling crane, a trolley thereon havingtransversely-rigid de pending supporting and lifting devices, aloading-pan, supporting means for fixedly supporting the pan in aninclined position under the lifting devices, said lifting devicesadapted to lift the pan from its support and tilt it so as to dump itscontents, substantially as described.

3. The combination of a crane with a trolley having trans versely-rigiddepending hangers provided with means for engaging apan, and means foroperating one set of said hangers so as to raise the pan from itssupport, substantially as specified.

4. The combination of a crane with a trolley having transversely-rigiddependinghangers provided with means for engaging a pan, and means foroperating one set of said hangers so as to raise the pan from itssupport, and then tilt the same, substantially as specified.

5. The combination of a traveling crane with a trolley having dependinghangers provided with means for engaging a pan, andelectrically-controlled locking devices for said engaging means,substantially as specified.

6. The combination of a traveling crane, with a trolley having dependinghangers for engaging a pan, the hangers for one end of ICC the pan beingrigid and those for the other SAMUEL T. WELLMAN. CHARLES H. WELLMAN.JOHN XV. SEAVER. THOMAS R. MORGAN.
